Physical
Description: Athletic, strong, durable frame. Long legs, high
waist. Not much room for physical growth.

Mechanics:
Works from middle of the rubber. Hands set at the belt. Brings hands to
chest with first move towards the plate. Three-quarters arm slot. Long arm
action in back with a slight wrist turn. Great balance over the rubber on
back leg. High leg kick with average extension towards the plate. Gets
over front side and pitches downhill. Has struggled to repeat at times in
the past, but beginning to demonstrate more consistency mechanically.

Fastball: 88-96 mph. Sits 91-94 mph generally. Can
dial it up anytime he wants it into the upper-90s, and will occasionally
work in some slower fastballs. Arm-side run when down in the zone. Gets on
hitters quick. Heavy, overpowering at times. Will elevate by design.
Effective ability to pitch to both sides of the plate. Command and control
steadily improving. Changes speeds. Easy plus pitch.

Curveball: 78-82 mph. Hard snap out of the zone. Solid-average
when he stays through it. Will flash plus on occasion. Tough pitch to
command in the zone and hitters can often just lay off. Does a good job
controlling it and burying it down. Pitch has a chance to be a plus
offering with improved consistency and command.

Changeup:
83-86 mph. Arm-side fade. Improving feel and confidence in pitch.
Maintains arm speed generally. Can tend to leave up in the zone. Average
pitch showing signs of improvement. Needs to improve command down in the
zone.

Career Notes: Both secondaries showed
marked improvement at the end of the 2014 season. Began the 2014 season on
the disabled list with shoulder soreness. Has also utilized a slider in
the past. Played for the Team USA Collegiate team after his sophomore
season. Was used as a relief pitcher for the first time during brief major
league call-up in 2014.

Summation: Middle to
back-end starter potential. Three-pitch mix with two potential
plus-pitches and future average command/control. Will need to improve
consistency of breaking ball and ability to command for strikes to reach
ceiling. Bulldog type with no-fear approach. Controlled aggression. Barnes
could fill an immediate need in the back-end of the bullpen where some
would argue is where he is best suited.
